308 barrels

[Tumbleweed]

H,

How close would an upper with this barrel and a carbon fiber tube come to the weight of your AR12s?

I was hoping you would put those into production, but couldn't afford one when you made the few you did. This may be my way to lighten my LR308 enough to enjoy hunting with.

will order one later today or tomorrow.....thanks!!!

any chance we'll see 16" in the future?

owenslee i think a 7mm08 would make for a awsome build. My most favorite caliber. Low recoil but alot of downrange energy at exteded ranges, with plenty of bullet selections. Very underestimated catridge.

Agreed...!

There is 4oz difference between the 12 I have but it's a thicker barrel.
I used a DPMS light receiver, carbon float, AR10 carrier and bolt 4lb 12oz for the upper only.
These barrels headspace on Armalite, DPMS and my 308 bolts.

If these sell ok I may do a 16".

One thing about AR10s and DPMS 308s etc when using a carbine stock a carbine AR10 buffer must be used and you can't just use any carbine spring. Some springs have more coils and will not allow the bolt to lock back so test the combo by hand to see if it locks back.

These barrels are ported .082, they run and lock back with a rifle system or a carbine system.

Armalite or DPMS bolts will work, both carriers will work in a DPMS receiver, either bolt will work in either carrier.
I try to use Armalite parts, just believe they are better quality and heat treat also like the spring on the firing pin.

For buffer and springs talk to that slash guy on AR15.com he helped me out with the one I needed to run a UBR on my rig.

Regarding these barrels, I have a MA-TEN receiver set and I have a few questions.

1) My understanding is that I need an Armalite bolt carrier and either an Armalite or DPMS bolt will work. Is this correct?

2) If I want to use a Troy TRX rail, which one do I need with this barrel? I read that the MA-TEN receiver matched to the rail height of the Troy TRX DPMS High rail. Will this rail work with the AR Performance barrel? I thought I read that the Armalite barrels used a different barrel nut?

3) Does this barrel require a standard AR-15 mid length gas tube? Again, I read somewhere that the gas tube length on the Armalite barrels was different than a standard AR gas tube.

Sorry for all of the questions. this is my first AR-10 build. Some people tell me I read too much,

The mid length gas tube is the same.
Rail? the one that fits the receiver you plan to use including the barrel nut, barrels don't have threads so they don't determine which barrel nut you use.
Any rail will work with the barrel, either DPMS or Armalite bolts will work with the barrel.

Thanks for the prompt response. I should have realized the part about the barrel. I can't wait to get this one finished!

Here are a few tibits I picked up doing my MA-Ten build that took some time to figure out:

The std DPMS barrel nut uses a std AR-15 armorer's wrench. Armalite requires its own special wrench.

For a buffer and spring, I used this tube:
VLTOR pt# RE-10
The RE-10 extension will only work when using the Armalite AR-10B Operation Spring, part# EA1095 and AR10 Carbine Buffer (H3) part# EC0120. The receiver extension has a MilSpec outer profile and will accept milspec dimensioned AR-15 buttstocks.

This tube is a little longer than an AR-15 tube. Going this way, you can use std parts. If you use an AR-15 tube, you have to get the special "Slash" buffer and modified spring that is over $100.
